This isn’t, like, a blink-and-you-miss-it gag that you have to go frame by frame to catch. Yes, I was in fact looking directly at the screen where they were prominently featured for several seconds.

It makes sense that a series centered around a sitcom actor would reference other tv series in a funny and obvious way.
At the end of season 1 we see Margo Martindale in prison with the cast of “Orange is the new Black” that was also pretty obvious if you knew the series, and the turtles are way more culturally relevant than that netflix series about lesbians behind bars.

OMG
